NONGLARE A TACHMENT r03 'HEADLIGHTS.

Application filed February 2'5, 1924. Serial No. 694,858.

To aZZ whom, it may concern:

Be it known that I, Lno J. GAGNON, a citizen of the United States, and resident of Detroit, in the county of ,lVayneand State of Michigan, have invented new and useful Improvements in Nonglare Attachments for Headlights, of --which the following isa specification. This invention relates to deflectors for headlight-s for automobiles, motor boatsand the like, and has for its primary objectthe provision of a. deflector that may be quickly attached upon the usual socket connection for the bulbs utilized in headlights and which will serve to deflect the light rays that would ordinarily reach the ,eyes of a driver approaching the headlight. I

Another object of the invention is the arrangement of a non-glare reflector be tween the lamp and the'usual parabolic reflectorof the headlight that will diffuse the light rays projected from the lamp so as to utilize them in illuminating the roadway in advance and at the sides of the automobile,

while cutting off those rays that ordinarily produce what is termed glare 1 A further object of the lnvention is the provision of a simple, practical, and com-' aratively inexpensive reflector attachment for headlights, which can be readily formed from a single sheet of metal and maybe securely fastened adjamnt the usual bulb to prevent rattle or accidental dislocation.

Other objects and advantages will be apparent from the following description, wherein reference is made to the accompanying drawings. illustrating a preferred embodiment of my invention and wherein similar reference numerals designate simi lar parts throughout the several views;

In the drawings:

Fig. 1 is a longitudinal sectional view through a headlight with my improved nonglare attachment in position above the bulb.

flector 6 in the center of which is secured the socket 7 for the reception of the usual headlight'bulb 8.; The. socket 7 is provided with a. pair of diametrically opposed bayonet slots 9 in which extend projecting studs 10 on the bulb, whereby the bulb will be firmly fastened in position by a direct thrust tothe rear of the bayonet slots andjthen a slight.

turn. These slots 9 are utilized'by. me for also'pos1t1oning my deflector 11. 1 Thus, as shown in F1gs. 1 and 4, a pair of rearwardly projecting tabs 12 on thehub portion of the deflector fit into the forward extremities of the slots'9 to hold the deflector in its desired I position, and are held in such slots'by' the pressure exerted on the deflector by the coil spring 13 encircling the bulb8 and engaging at its extremitiesagainst the hub portion of the deflector and the flaring rearportion of the'bulb. I

-,My, improvednon-glare deflector is best shown in Figs. 1 and 3, and comprises a p substantially semicylindrical reflecting portion 11 of'metal having a polished or coated surface adapted to reflect the light rays,a

= hub portion 11? adapted to encircle the bulb 8 and neck portion 11 connecting the hub and reflector portions. Preferably my improvedfdeflector is stamped froma single sheet of aluminum or other. suitable. metal;

and then shaped; to substantially the, configuration shown in Fig. 3', with the neckpor- 7 tion 11 as narrow as is feasible so that very little surface of the reflector 6 will be covered thereby. The hub portion 11 is provided with a pair of diametrically opposed notches 14 to permit the passage of the projecting 1 studs 10 of the bulb 8 through the central opening of the hub portion.

In practice, the coil spring 13 is slipped over the bulb 8 and the bulb is inserted through the hub portion 11 of my deflector, and is then pushed into the sockets 7 with its projecting studs 10 entering the slots '9 of'the socket. Just before the bulb 8 is in its rearmost position the deflector 11 is.

turned to bring its rearwardly projecting tabs 12 into the forward portions of the slots 9. The bulbis then pressed to its rearmost position and turned to locking position .in the curved portions of the. slots. In so doing the coil spring13 is compressed between the flaring portion'of the bulb and the front'face'of the hub portion of-the deflector, and the pressure ofthe spring in this position serves to maintain the tabs 12 in the slots 9 as well as to hold the hub portion of the deflector in firm engagement with the reflector 6'. In Fig. 1 I haveshown the deflector 11 in position above the bulb 8, While in Fig. 2 I have shown the deflector in position below the bulb 8.- It will be apparent that to maintain such positions it is only necessary to reverse the tabs 12 in the slots 9.

With the deflector 11 in the position shown in Fig. 1, the light rays from the bulb 8 that ordinarily project through the upper half of the headlight into the eyes of persons ahead of the car will be cut oil and deflected downwardly onto the road shortly in advance of the car. Also certain of the light rays that would impinge against the upper half of the reflector Gand then be reflected forwardly and upwardly would be prevented from reaching the reflector 6,

instead of being diffused over the the lower half 01 the headlight. Sometimes it happens that the reflector 6 is so shaped or positioned that light rays impinging against the lower half of the reflector are thrown forwardly and upwardly suliicientl-y to cast a glare in the eyes of approaching drivers. Turning my deflector 11 to the position shown in Fig. 2 will remedy this. The light rays from the bulb 8' that would ordinarily impinge against the lower half of the reflecto-r G will then be cut ofli by my deflector I1 and difi'us'ed over the upper half or the reflector 6, whence they are thrown forwardly and downwardly.

My improved deflector will be securely held in either position as long as desired without danger of rattle or accidental dis location but can be immediately removed whenever desired by simply turning the bulb in its bayonet slots and then pulling the bulb with the deflector thereon forwardly from the reflector.

While it will be apparent that the illustrated embodiment of my invention herein disclosed is well calculated to adequately fulfill the objects and advantages primarily stated it is to be understood that the invention is susceptible to variation, modification and change within the spirit and scope of the subjoined claims.

Having described my invention, I claim 1. In combination with a headlight re"- flect'or having a central socket provided with a pair of diametrically opposed bayonet slots and an electric lamp having projecting portions adapted to enter said slots a deflector having a hub portion surrounding the lamp and provided with a pair of notches for the passage of the projecting portions of the lamp, said hub portion being also provided with a pair of rearward-1y projecting tabs adapted to seat in said slots, and a spring arranged to hold the deflector with its tabs positioned in the slots.

2; In combination with a headlight reflec= tor having a central socket provided with diametrically opposed slots, a bulb secured in the socket, deflector comprising an in tegral deflecting portion spaced from and adapted to partially encircle the bulb, an apertured hub portion and a neck portion connecting the hub and deflectingp'ortions the hub having a pair of rearwardly ext-end:

ingtabs arranged to fit in the slots of the socket.

In witness whereof I hereunto set my hand.
